Description

A kind of high reliability radio frequency (RF) coaxial connector of fast demountable
Technical field
The present invention relates to the technical field of connector for radio-frequency coaxial cable, specially a kind of high reliability of fast demountable Radio frequency (RF) coaxial connector.
Background technology
The most commonly used is installing type, welded type and compression joint types with cable connector form for radio frequency (RF) coaxial connector in industry.Needle To installing type structure, all it is screwed on by screw thread to realize, can be dismantled in industry.The connector of installing type structure is compared Other two kinds of constructed values are partially expensive, but the advantage is that the using flexible in engineering construction, can be according to physical length or interface Form demand adjusts.According to investigation, construction personnel's one connector of installation that one skilled in engineering construction needs cost 2 ~3 minutes, for a new person, 10~15 minutes will be spent substantially by installing a connector according to instruction for mounting, Er Qieke It can also install not in place, performance indicator is bad.
The connector internal structure of same model is substantially similar both at home and abroad now, is highlighted in terms of electric property Problem is also almost the same, the more dynamic intermodulation of concern especially in industry.The problem of for dynamic intermodulation, we also pass through More analysis of experiments removes material and plating problem, clamping and connector plug jack of the connector cable folder to cable outer conductor Play the role of large effect to intermodulation to the holding capability amount aspect of cable inner conductor.Conventional connector is to cable outer conductor The gap of only simple clamping, remaining position and cable outer conductor is bigger, and in the dynamic case with regard to cable outer conductor Shaking can cause intermodulation extremely unstable, and same problem also appears in inner wire clamping, therefore the two factors are to dynamic intermodulation Stabilization play vital influence.
Requirement with base station system to various components performance is higher and higher and the continuous improvement of artificial construction's cost, very much The stable and easy to install connector development plan of performance is all being found by external producer.
